H1 XTR HID Bulbs: Inserting HID bulbs into halogen designed H1 bases requires extreme accuracy. Each XenonDepot H1 HID bulb is laser aligned into its P14.5s (H1) so that the focal point of the HID bulb precisely matches the focal point position of the H1 halogen bulb, ensuring optically correct beam patterns. Whether you plan on installing this H1 HID bulb into your vehicle's fog lights or fog lights, you can be certain that light is going to go where it's meant to be!
Xtreme HID Bulbs: Xtreme HID bulbs are manufactured from high quality, German made Philips UV quartz glass to ensure you don't prematurely age your vehicle's fog lights. Many other HID bulbs use low grade glass that simply won't protect your vehicle's fog lights from the UV light HID bulbs emit. Each HID bulb will come with high quality insulated wires that will enable you to plug the HID bulb into a 35W-HID ballast (with AMP style connectors). You will also get additional wiring to connect your ballast into your vehicle's OEM fog light harness with a true matching connector, making this a proper plug+play application!
Lifespan: Average lifespan of these Xtreme HID bulbs is roughly 2500 hours--on par with OEM manufacturers such as Philips or Osram. These HID bulbs are sold in pairs to ensure your fog lights match in color as HID bulbs do color shift over time.
